[RESEND PATCH net-next v4 14/25] net: fman: Inline several functions into initialization

From: Sean Anderson
Date: Thu Aug 18 2022 - 12:19:30 EST

There are several small functions which were only necessary because the
initialization functions didn't have access to the mac private data. Now
that they do, just do things directly.
